A shy musicologist from Iowa (Ryan) travels to San Francisco with his fiance (Kahn) for a convention. He meets the eccentric Streisand at his hotel and becomes involved in a chase to recover four identical flight bags containing top secret documents, a wealthy woman's jewels, the professor's musical rocks, and Streisand's clothing. Bogdanovich's homage to the screwball comedies of the '30s. Kahn's feature film debut.
